You might seen the unique set of pioneer colour photos taken by Russian photographer Prokudin-Gorskii a century ago. Here is a new portion presented on BBC.

"This vivid colour photograph is 100 years old, a self-portrait by the Russian aristocrat Sergei Mikhailovich Prokudin-Gorskii, using a unique photographic technique he developed himself. Prokudin-Gorskii studied chemistry under Mendeleev, the inventor of the periodic table, before travelling to Berlin to study photochemistry.'

Prokudin-Gorskii took thousands of pictures between 1909-1912 as he toured the Russian empire, armed with a special pass from Tsar Nicholas II. He created a panorama of all the peoples, landscapes, industries and antiquities under Russian possession.
